Patented lJan. 7, 1930 UNITED STATES PATENT OFFICE WILLIAM ROPER, OF BALDWIN, NEW YORK, ASSIGNOR OF ONE-HALF TO THOMAS S. GASSNER, OIE PHILADELPHIA, PENNSYLVANIA GASEMENT WINDOW Application filed September 19, 1928.

My invention relates to easement windows, and more particularly to those of the reversible type.l

Casement windows of the reversible type as previously constructed have certain inherent disadvantages which often render them unreliable and unsafe. For example, it is customary for such windows to be solely supported by side hinges when in reversed or open position, and corrosion or shearing ofl the hinge pintles due to sudden shock might in such cases cause the window, which may be very heavy for certain types of buildings, to break loose from its hinges and fall, causing damage and possible injury to people un'- derneath. Furthermore the hinges and supporting members for windows of the above type have generally been exposed to the weather with resulting corrosion, deterioration and weakening of the supporting structure.

In accordance with my invention, there are provided a plurality of levers for bodily supporting a easement window of 4the reversible type, the said levers being adapted to lie within recesses formed in a supporting frame when the window is in closed position.

Further and more specifically in accordance with my invention, the said supporting levers have lugs mounted thereon adapted to engage the movable frame member of the window to restrain movement of the same with respect to said levers and to maintain the same in closed position; the said lugs each having a locking member thereon adapted to engage a'coacting locking Ymember mounted on said movable frame, andthe said locking structure having .common actuating means so that said frame may be releasedV from said lugs by a single operation.

For a better 'understanding of my invention, reference is to be had to the accompany# ing drawing in which:

Fig. 4 is a plan view of the window in closed position.

Fig. 5 is a plan view of the window in'both open and reversed positions.

Fig. 6 is a detailed view of locking structure.

Referring to Fig. 1, which shows a reversible easement window of the pivotedlever type as viewed from the outside, a stationary frame 1 has secured thereto lug members 2 (Fig. 6) having bearing members 3 for supporting levers 4. Framel 1, as disclosed, is rectangular in shape and the top and bottom sections are each cut away as at 5 (Fig. 4) to provide recesses for levers 4. A detachable cover plate 6 is secured, as by screws 7 to the frame so that the upper lever may be completely shielded and protected when the window is in-closed position.

A window 8 mounted in frame 9 is adapted to be supported by levers 4 adjacent their Jfree ends, and has bearing members 10 secured thereto, as by screws 11, for co-operating with pins or studs 12 secured to the pivoted levers. Levers 4 are pivoted to the frame 1 by pins or studs 13 secured to the levers, which are mounted in bearing members 3. Itwill be observed that levers 4 are mounted so that their planes are substantially parallel with their planes of movement. This construction results in certain advantages which will be later described.A

Secured to levers 4 are lugs 14 which are adapted to engage the frame 9 of window 8 when the same is pivoted at 12 in a counterclockwise direction 'as viewed in Fig. 5. Reerring to Fig. 6, each lug 14 has mounted thereon a pointed locking element or stud 15 having a recess 16 cut therein for engagement with a co-operating locking element carried by pivoted frame 9. The edge of frame 9 which is adapted to bear against lugs 14 has a hole 17 therein opposite each. locking stud 15, and isfadapted to receivefstud 15 when the window is rotated to the position indicated in Figs. 1 and 4. Frame 9 has an outer flange 18 secured thereto, the same normally being on the outside ofthe window and has on its inner edge adjacent lugs 14 locking structure 'for zo-operating with studs 15. The locking structure comprises a continuous member, as a rod 19 eX- tending vertically along flange 18 between the holes 17 therein, and is guided for reciprocal movement by any suitable means as screws 20. cofacting with slots 2 1 in member 19. Av knob, or equivalent, 22 is secured to member 19 so that the same may be reciprocated vertically along fiange 18. Member 19 has holes drilled there-through at its` opposite ends` in suchregistry with holes 17 that when the studs 15 are inserted through ysaid holes, member 19 is adapted to moveto its lower position and seat within, recesses 16 of studs 15 so that relative movement between lugs 14 and window frame 9 SPIG- vented. The member 19, which ,will4 be termed a. locking/bar, ispermittedr through guide means 2O and21 to e in such position when the window and itssupporting levers are not locked together that holes 23 are not in exact registry with holes 1T, but` are slightly below the same so that. the pointed end of stud lserves tol cam locking bar 19 upwardl as it enters holes 1;7 and 22p.V Vyhen stud 15, as moved to such position; that. lug le is in close engagement with 11e-nge 1.8, recess 16 oflug 15 will bein exact registry with locking bar v19, which will thereupon fall into Said recess and. effect kicking f Vlevers 4 andframe 9.VV

It will therefore be apparent that when frame 9 Vis locked tov levers4 in the manner previously described, the window 8 will pivotabout pivots. 13 audits. movement will be that of the ordinary sideivoted window. For such usual use, the window is provdd with conventional fastening structure 24 for securing the Window from the inside to sta-Y tionary frame 1.. Such fastening means may be of any desirable type, and'may compr1se an operating handle 2o for moving lever-,2 6v

secured thereto into engagement with an .inner flange 27 of frameA 1. In, the position shown in Fig, 1, the window is unlocked on by counter-clockwise movement of arm 25.

Conventional means for securing the window injvarious open positions comprise a lever 28 pvoted'et 29 t0 frame.` 1 andhaving et its opposite' end a thurrib screw. 3Q, or equlvelent, for er1-operating with a member 3l Slid- -ablexeu bar 32. which is Secured to frame 9-` VFurther descr.ptcn of this feature is deemed umlecessary,i such construction being Well known in; the art.. Thumb screw 30. is Simply Leosened wheuthe. window iS to be moved te d iiereut positions... and' tightened when the .desired peiiieuis reached, it only being necessary-tc remember. that levers 2.8 and 3,2 must; vbe dieceuuectedl by lecseung Screw 30 when. the Window '1e-12in.Y .be reversed about 1i. new it becemee desirable t0 reverse. windem die? the Purpose ci cleaning; the cuter the inside, the window being fastened simply` derstood that sui-table fastening means ma be provided for securing thewindow in di ferent reverse positions. For example, when the Wind is in such direction that it would be undesirable to have Window 8 open when ptvoted in its usual manner,it will be apparent thatthe window may be reversed and madeto open in the opposite direction as indicated in Fig. 5 soV that the kprevious object-ions are overcome. For such reverse positions, suitable fastening structure may be mounted on frame19, as on flange 18, to c o-act with the securing lever 28. i

By referring to Figs. 4 and 5, it will be noted that the weight of window 8 is not o borne by the pivots 12, but is borne directly by the offset portions 4a.' of levers4. By designing levers 4 so that the weight of window 8 is directly borne by them, the pivot pins 12 are relieved' of the great stra-ins and stresses g5 due to shearing forces exerted whenthe winf 3 dow isopened or closedwith great force, as is often the case in actual practice.y Furthermore byiproviding recesses5in the topi and bottom portions ofy frame 1 forl receiving 100 levers 4, the same are protected when in H closed position against the deteriorating ef- Y fects of the. Weather and from mechanical Vinjury. In addition, the. aforesaid structure presents an improved a pearance over other types of hinged `reversi lewindows as large 'l unsightly hinges. are eliminated.V In reversible Windows of the vhinge type, it is. apparent that the hinge pintlesare continuousl exposed to the deteriorating effects. of the no weather, and since the mechanical shOCk is transmitted directly through the pintles between the windowand 'its frame, the said pintles will in tiinebecome unsafe and there willbefdanger of the window falling from its fastening's. In accordance with mH `inventt/in.,how-` ever, t-he window.i is not inged, within the ordinarily accepted meaning of the term, but is pivotally supported on a pair of levers which inV turn are pivoted. to a stationary frame. V l f The locking structure for. maintaining frame 9l in engagement With levers 4 has other advantages than enabling the window to be used as an ordinary side-hung window. Since levers 4' may be independently: mount ed on frame 1, it is desirable that the action of bothv the topY and.V bottom pivots be synchronized. As frame 9 is of necessarily rigid construction, it follows that when both levers 4 are fastened to the said frame, synchronized movement will result. It is also both highly desirable and essential to have the portion of frame 9 opposite fastening means 24 and 25 in tight engagement with the stationary frame l, so that the window may not be opened from the outside by moving the saine about pivots l2 in a counter-clockwise direction as viewed in Fig. 4. If suoli operation were possible, fastening means 24 and 25 would have but little use. By providing lugs 14 on levers 4, however, for overlying liange 18, it will be apparent that the window may be maintained in snugly closed position when fastened from the inside. By further providing locking means for restraining movement between levers 4 and frame 9, play or rattle between said members is taken up and prevented.

It will be understood that my invention is not limited to the specific structure herein described, but is applicable to top-hung, as well as side-hung frames such as transoms, for example, and that the same is applicable to any pivoted frame structure which is to be reversibly mounted.
